JOHN G. W. PUTNAM, OF SARATOGA SPRINGS, NEW YORK.

COAL-SIEVE.

SPECIFICATION forming part of Letters Patent No. 287,161, dated October 23, 1883.

Application tiled March 30, 1883.

To a/ZZ whom it may concern:

Be it known that I, J. GEORGE W. PUTNAM, of Saratoga Springs, Saratoga county, and State of New York, have invented a new and Improved Coal-Sieve, of which the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved coal and ash sieve, which is so constructed that the coal and ashes can be sit'ted with very little labor and the spreading of the dust is avoided.

This invention pertains to an improvement in coal-sieves; and it consists of the combination and construction of parts, substantially as hereinafter described and claimed.

Reference is to be hadto the accompanying drawings, forming part of this specication, in which similar letters of reference yindicate corresponding parts in both figures.

Figure 1 is a crosssectional elevation of my improved coal-sieve, showing the same in position for filling it. Fig. 2 is a sectional plan view ofthe same oh the line x x, Fig. l.

A drum, A, made of wire-netting or perforated metal plates or analogous material, is journaled in a box, B, and is provided with a crank-handle, O, outside of the box. The drum is provided with a hinged door or gate, D, parallel with the axis of the drum, which gate is provided on its upper surface with a pivoted latch, E, having one end bent' upward. The other end is adapted to be passed' into a groove, c, in the edge of a strip, F, against which the swinging end of the gate D rests when it is closed, whereby the said gate can be locked. The drum is provided with a longitudinal or radial partition, G, extending from the axis of the drum to the hinged edge of the gate. The box E is provided with a hinged cover, H. The front of the box is provided with a downwardly-swinging gate, J I provided at each side with an inwardly-pro,- jecting flange, K, to form a chute, and at its swinging end with a pivoted button, L, for4 locking the gate. The bottom of the box B is provided with a sliding plate, M. A circular board, N, is secured to the box a short distance above the lower end of the same.

The operation is as follows: The cover H is' raised and the gate D is swung upward and (No model.)

outward, and is held in position by the latch E, the bent end of which catches on the upper edge of the front of the box B. The coals and ashes are then dumped into the drum and the gate D is closed and locked by means ofthe latch E, and the coverH is swung down. The drum A is'then rotated, and the ashes drop through the meshes of the same on the plate M, the cinders and coals remaining in the drum.

Then the gate J is swung down and the drumv is turned until the partition G is in the position shown in dotted lines' in Fig. 1, andthen the gate D is swung down. The coals and cinders slide down the gates D and .T anddrop into aba-sket or other receptacle placed below the lower edge of the gate J. As the box B isentirely closed while sifting the coal and cinders, thedust will be retained in the same and cannot spread. The box B, after the removal of the plate M, is placed in an ash-barrel, &c.,which is covered by the board N, which prevents the dust from spreading when the ashes are 'permitted to drop into the barrel.

On the under side of the lid H a strip, O, is secured, which can be used as a handle in carrying the coal-sieve.

Having thus described my invention, l claim as new and desire to secure by Letters Patentl. In a coal-sieve, the combination, with the rotatable sieve, of the radial board arranged in said sieve, and the gate hinged to the upper end of the radial board, and adapted to rest upon the upper edge of the sieve-inclosing receptacle, to be secured to screen-strip F and to unfold and form an extension of the ,radial board, both when the sieve is iilled and when emptied, substantiallyas and for the purpose \set forth.

2. In a coal-sieve, the combination, with the box B, of the cylindrical sieve A, journaled on the same, the hinged gate D, the strip F, provided with a groove, a, in its edge, and the latch E, pivoted on the gate D, and having one end bentV upward, substantially as herein shown and described, and for the purpose set forth.
